I put in a new motor 8V92 in my 89 MCI102C3. (Well new to me).
Plugged in all the wiring and now when I depress the brake pedal the temp gauge and volt gauge go crazy and go to zero. After a while they return to normal.
Any one have any ideas???
Gremlins are on the loose!!!!
Actually anytime multiple things happen I first suspect grounds.
Is this a DDEC engine?
